1.) It has already been built in Javascript. If it hasn't, somebody will build it in Javascript. Also see: Atwood's law.
2.) 'Frontend developers' will face their fear of the backend eventually.
3.) Just use MySQL. The world is run on MySQL.
4.) Write text, structure it with semantic HTML, and then write CSS. Do not do these in reverse.

7.) Write really bad code in order to get better at it.
8.) Use lateral thinking. Sometimes Sublime text is bringing a gun to a knife fight. You could probably solve 90% of problems without a text editor.
9.) Don't build it yourself.
10.) Refactor only when you know the code has bugs. Refactoring is better than obfuscated code.
